FILLING-REPLENISHING MECHANISM.

Specification of Letters Patent.

Patented Qct. 18, 1910.

Application led October 23, 1909. Serial No. 524,152.

To all whom it ma/y concern:

Be it known that I, JONAS NoRTHRoP, a citizen of the United States, residing at Hopedale, in the county of Vorcester and State of Massachusetts, have invented an Improvement in Filling-Replenishing Mechanism, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter described relates to looms and more particularly to looms of the filling replenishing type.

Looms of the filling replenishing type are well known and in common use, and are ordinarily provided with a transferrer to transfer a filling carrier from the supply to the weaving elements when the filling becomes broken or reaches a condition making a transfer desirable. The transferrer is ordinarily controlled by a train of mechanism including a detector of some kind, which, when it detects a condition of filling that renders a fresh supply desirable, causes the train of mechanism to assume operative relation with respect to a moving part of the loom and eiect a transfer.

It is desirable that the transferrer engage the filling carrier to be transferred near the base and near the tip, but in such construction if the shuttle fails to be properly boxed, as, for instance, should it fail to enter the box sufficiently or rebound therefrom, the tip of the filling carrier may strike the end of the shuttle and be prevented from entering the shuttle chamber, in which case the transferrer or some other part is liable to be broken. It is likewise desirable at times to render the transferring mechanism inoperative, as, for instance, during adjustment by the loom fixer when a shuttle is found to be not properly boxing or for other reasons, as will be readily understood by those skilled in the art. Y

With these matters in view, the aims and purposes of the present invention are to provide means for preventing breakage of the transferrer or other part when the shuttle fails to be properly boxed at the time of transfer and to furnish simple and effective means whereby the transferring mechanism may be readily made inoperative at the will of the attendant or others, all of which will best be understood from the following description and accompanying drawings of one form of means for putting the invention into practical eiiect.

In the drawings: Figure 1 is a section on the line l-l of Fig. 2 showing one form of transferring mechanism associated with the present invention; Fig. 2 is a section on the line 2 2 of Fig. l; and Fig. 3 is a detached detail showing the latch controller.

Although the present invention is generally applicable to any form of filling replenishing loom, it has been shown herein as applied to the character of loom and filling replenishing mechanism set forth in my prior application Serial No. 516,240, filed September 4, 1909.

The loom frame 1 having the breast beam, the bracket 2 secured to the loom frame by the bolts 3 and having the webs 4 and 4X for supporting a hopper 5, the slot 6 for the passage of the filling ends, the back wall 7 of the throat 11, the slide 9 movable on the web or shelf 8 and having the front wall 10, the spring 12 acting to hold the slide in forward position, the filling carrier positioner 13 mounted at 111 and having the carrier engaging end 15, and the means for operating said positioner may be as fully set forth in the said prior application, or such parts may be modified as desired, it being understood that the invention is not circumscribed by these details.

Mounted in a bearing 16 supported by the bracket 2 is the stud 17 preferably secured in said bearing by screws 18, or otherwise.

Loosely mounted on the stud 17 is the hub 19 of the transferrer, the arm 20 of which projects from said hub and has a carrier engaging end 21, Fig. 1, substantially as in the application referred to. The arm 20 carries a pin 22 which acts upon the end 23 of the filling carrier positioner, a spring 241 normally acting to lift said arm 23, substantially as in said application.

The transferrer arm 20 is normally held in raised position, as indicated in Fig. 1, by means of a spring, the tension of which may be adjusted by means of adjustable connection with the stud 17, as shown or by other suitable means.

Loosely mounted on the stud 17 is the arm 26, the end 27 of which acts as a stop for the ti s of the filling carriers, and when the trans errer is depressed, as will hereinafter more fully appear, this end of the arm 26 drops upon the top of the shuttle box -and its front edge acts at this time as a guide for the tip of the carrier as it moves into the shuttle chamber, substantially as in the said application.

Projecting from the transferrer arm 2O are the lugs 23,28, between which extends a pin 29 on which is mounted the hub portion 30 of the tip engaging member of the transferrer. This tip engaging member in the form of the invention shown comprises an arm 31, the outer end of which has a head 32 to engage the tip portion of a filling can rier when it is to be transferred to the shuttle, said head being also provided with the lugs 33 and 34 to coact with the lug 35 projecting from the end 27 of the arm 26, which for identification may be termed the tip stop and guide.

Extending from the hub 30 of the tip engaging member 31 is a lug 36 between which and a seat 37 on the transferrer arm 2O extends the spring 3S normally acting to separate the lug 36 and seat 37, a suitable stop 39, Fig. 1, on the member 31 coacting with a similar stop on the transferrer arm 2() to limit movement of said member 31 responsive to the spring 38. From the construction thus far described it will be noted that upon downward movement of the trans ferrer arm 2O to transfer a filling carrier from the source of supply to a shuttle, the tip engaging member will also move in the same direction, but should the tip of the filling carrier meet an obstruction or be p revented from movement in response to the action of the transferrer, the tip engaging member will yield and prevent breakage. As the transferrer returns to initial position, the spring 38 will restore the tip engaging member to proper posit-ion with respect thereto. Such obstruction to dmvnward movement of the tip member of the Jtransv ferrer may be caused by the shuttle not having entered the shuttle box sufficiently or by its having rebounded therefrom, in either of which cases the tip of the carrier may strike the end portion of the shuttle, but in any event, regardless of the cause which prevents the tip of the carrier from responding to the action of the transferrer, the tip member is yieldingly held so that it may yield and prevent breakage when its movement is obstructed.

Improper boxing of the shuttle may call for the attention of the loom fixer, and during the time he is adjusting the parts to secure proper action it is desirable that the filling replenishing mechanism be rendered inoperative.

Y Extending downward from the hub 19 of l the transferrer is the arm 40, Fig. 1, to which at 41 is pivotally connected the latch carrier 42 carrying the latch 43, suitable means,

such as the adjusting screw 44, being provided for properly positioning the latch in its carrier for coperation with the usual bunter carried by the lay.

Adj ustably secured to the usual transverse shaft by the set screw 46 is the latch actuator 47, adapted to raise the latch 43 into the path of the usual bunter when the transverse shaft 45 is turned under'the direction of the usual detecting mechanism, as will be -readily understood.

Extending from the upper portion Vof the actuator 47 is a part 49, Fig. 1, and pivotally connected at 51 to the actuator is a finger 52 normally held in full line position, Fig. 1, by a spring 53 secured to the actuator by a securing screw 54, or otherwise. The free portion of the spring is adapted to bear upon either the shoulder 55 or the shoulder 56 of the linger 52, the construction being such that when the finger 52 is in full line position, Fig. 1, it is held in such position by the spring 53, a pin 50 projecting from the latch carrier extending between the part 49 and finger 52. lith the parts in this related condition, if the transverse shaft is turned contracloekwise viewing Fig. 1, it is evident that the actuator will turn the latch carrier on its pivotal support 41 and place the latch 43 in position to meet the bunter, as usual; but should the finger 52 be turned into dotted line position, Fig. 1, into which position it may be moved by the attendant or loom fixer by simply overcoming the resistance of the spring 53 on the shoulder 55, it is'equally evident that any upward movement of the actuator will fail to turn the latch carrier, so that notwithstanding the detector may indicate a condition of felling requiring replenishment and turn the transverse shaft, the latch will not be placed in position to be actuated. The parts may thus remain in inoperative relation while the loom fixer is adjusting the loom parts or experimenting with the loom to secure the desired action thereof and proper boxing of the shuttle, and may then be returned to operative relation by simply swinging the nger 52 from dotted line to full line position, Fig. 1.
